Of course, I regularly obtain 200 watts of forward
power from my 100 watt IC-706. It's all due to
constructive interference.

Nice try, but you're kidding yourself if you think you're getting 200
watts out of an IC706.

Back to the laser example, the answer you can't seem to get right is
that, recombing the split beam back into one beam will at best recover
1 watt of laser power. That's the limit allowed by conservation of
energy as it happens.
